Question

what is the mass of one electron

Answer 1

The invariant mass of an electron is approximately9.109×10−31 kilograms, or5.489×10−4 atomic mass units. On the basis of Einstein's principle of mass–energy equivalence, this mass corresponds to a rest energy of 0.511 MeV. The ratio between the mass of a proton and that of an electron is about 1836.

Answer 2

hi ..

the mass of one electron is 9.110 x 10-28 g.


hope this helps ☺️☺️
